We run Xmx at the JVM limit of 2048m in our [EMAIL PROTECTED] production.

Very interesting. I just changed our web server JVM options from:
-Xms128m –Xmx256m
To:
-Xms128m -Xmx512m
and it corrected the heap space error. I’m worried though,
because we are getting ready to load thousands more documents into
DSpace and I’m wondering at what point we will start getting this
error again. I agree with François that it appears DSpace is
cycling through every record in the Collection doing something (I’m
not sure what since I was just updating the Collection description)
and because there are 44,938 records in this Collection and the
Java heap space was filled up.

Unfortunately, I agree with Susan.
We have a 300K items collection that we cannot upgrade (only
changing the description is not possible).
It happens only on THAT collection (and not on the other ones in
the same DSpace 1.4.2).
I did not look far inside, but it seems that DSpace loads all the
documents of the collection to be updated during the update!
I'm not on that problem right now.

Which memory settings might be too low?
I'm thinking it has to be related to the increased number of
records in our database since this is the first time I've ever seen
the error and because it doesn't happen in our test instance (where
our source code mirrors our production system). I can't imagine
though, what could be happening in edit-communities where all we
are trying to do is update one row in the collection table….??

This can be caused by something else happening on the server.
Basically your instance has used up its JVM heap space and any new
calls into the system results in an OutOf Memory error. Of you can
restart and try the task again, you may find that the issue is
gone, if its still there, then you have an issue that being cause
by your request more specifically. Monitor/Search your dspace logs
and see if you have more occuarnces of this than this one case. It
may either mean:
1.) your memory settings are too low.
2.) something is causing a memory leak, i.e. not releasing its
resources or falling into infinite loops.

I am getting an error while trying to update a Collection
(collection name and description) – see below from dspace.log.
This is the first time I've seen this error. The strange thing is
that it doesn't happen in our Test instance – but our Test instance
only has 101 Items in it. We've recently been adding lots of new
items to our repository and our Item count is now at 90,490. This
is kind of scary, since we have thousands and thousands more items
we are planning on adding to DSpace in the next few months.
We are currently running 1.4.2 and are planning to implement 1.5 soon.
Can anyone help with this error?
Thanks,
Sue
